ABSTRACT:
An antenna arrangement consists of a dipole radiator which is fed via a Triplate three-layer transmission line. The dipole is arranged to radiate and receive plane polarized electro-magnetic radiation having a plane of polarization which is determined by the orientation of an elongate slot in the dipole radiator. The Triplate is coupled to the dipole so as to maintain a substantially constant impedance over a reasonably wide bandwidth. A large number of similar dipole radiators can be mounted side by side and fed from a common Triplate structure and in this latter case a common reflector is used for all dipoles and is mounted on the Triplate structure itself.
